DETAILED DESCRIPTION OF THE INVENTION Synthesis

The compounds of Formula I can be prepared as shown in Equation 1 by the reaction of the appropriately substituted sulfonamide of Formula II with the appropriate methyl carbamate of a heterocyclic compound of Formula III in the presence of an equimolar amount of trimethylaluminum. ##STR10##

The reaction is carried out at 25° to 40° C. in a solvent such as methylene chloride for 10 to 96 hours under an inert atmosphere as taught in EPO Publication 82,681. The required carbamates III are prepared by reacting the corresponding amines with dimethylcarbonate or methyl chloroformate in the presence of a strong base.

Sulfonamides of Formula II where L is L-1 and R₁ is H can be prepared as shown in Equation 2. ##STR11##

Following the general procedure of Y. Girard, J. G. Atkinson and J. Rokach, J. Chem. Soc. Perkin I. 1044 (1979), the appropriately substituted indoline in a solvent of nitromethane or nitroethane is treated with chlorosulfonyl isocyanate (CSI) at -40° to 0° C. followed by warming to 25° C. Aluminum chloride is then added and the solution heated to 100°-120° for 1 to 4 hours. Addition of water results in the isolation of V. Hydrolysis of V in aqueous acid results in the isolation of IIa. Sulfonamides of Formula II where L is L-3 and R₁ is H can be prepared in a similar fashion from the corresponding tetrahydroquinolines.

Sulfonamides of Formula IIc where L is L-2 can be prepared by dehydrogenation of sulfonamides of Formula IIb where L is L-1 and R₃ is H, as shown in Equation 3. ##STR12##

Both catalytic and chemical methods are effective in dehydrogenation of indolines to indoles. The most common reagents are palladium-on-charcoal, quinones such as chloranil and dichlorodicyanoquinone (DDQ) and manganese dioxide as described in The Chemistry of Heterocyclic Compounds, Vol. 25, "Indoles, Pt. 1", W. J. Houlihan Editor, Wiley-Interscience, 1972.

Sulfonamides of Formula IId where L is L-1 and R₁ is C₁ -C₃ alkyl or C₃ -alkenyl can be prepared as shown by example in Equation 4. ##STR13##

The reaction of Equation 4 is carried out according to the procedures of G. W. Gribble et al., J. Am. Chem. Soc. (1974) 96, 7812. Sulfonamides of Formula II where L is L-3 and R₁ is C₁ -C₃ alkyl or C₃ -alkenyl can be prepared in a similar fashion.

Indolines of Formula IV where R₃ is H can be prepared from the corresponding indole by the procedure of G. W. Gribble and J. H. Hoffman, Synthesis, (1977) 859, as shown in Equation 5. ##STR14##

Other methods of preparation of compounds of Formula IV are found in The Chemistry of Heterocyclic Compounds "Indoles" Pts. 1-4, Wiley-Interscience, as are the methods of preparation of the requisite compounds of Formula VI.

Tetrahydroquinolines of Formula VIII where R₃ is H can be prepared from the corresponding quinolines by the procedure of G. W. Gribble and P. W. Heald, Synthesis (1975) 650, as shown in Equation 6. ##STR15##

Other methods of preparation of compounds of Formula VIII are found in The Chemistry of Heterocyclic Compounds, "Quinolines", Parts 1 and 2, G. Jones Editor, Wiley-Interscience, 1977, 1982, as are the methods of preparation of the requisite compounds of Formula VII.

Indolines of Formula IV where R₂ and R₃ are CH₃ can be prepared as described by Paol and Landenheimer, Ber. 25, 2974 (1892).

The carbamates of Formula III in Equation 1 are also important intermediates for the preparation of the compounds of this invention and are described below.

Preparations of 3-amino-1,2,4-triazoles of Formula (IIIf) are known in the art and 1,2,4-triazoles are reviewed in The Chemistry of Heterocyclic Compounds "Triazoles 1,2,4" (John Wiley and Sons, New York, 1981). ##STR19## Commonly used starting materials containing nitrogen are N-aminoguanidine, hydrazine, alkylhydrazines, cyanamide, ethyl cyanoacetimidate, dimethyl cyanodithioimidocarbonate, dimethyl cyanoimidocarbonate, ethoxymethylenecyanamide, and acylhydrazines. Some literature synthesis are illustrated below. Using these techniques or suitable modifications that would be apparent to one skilled in the art, the 3-amino-1,2,4-triazole intermediates can be readily prepared.

Heating equimolar amounts of ethyl propionimidate hydrochloride and N-aminoguanidine nitrate in pyridine gives 3-amino-5-ethyltriazole; German Pat. No. 1,073,499 (1960); Berichte, 96, 1064 (1963). ##STR20## Condensation of hydrazine with ethyl N-cyanoacetimidate yields 3-amino-5-methyltriazole; Journal of Organic Chemistry, 28, 1816 (1963). ##STR21## U.S. Pat. No. 2,835,581 (1958) teaches the preparation of 3-amino-5-(hydroxymethyl)triazole from N-aminoguanidine and glycolic acid and British Pat. No. 736,568 (1955) describes the synthesis of 3-amino-5-mercaptotriazole. Condensing hydrazine with dimethyl cyanodithioimidocarbonate in acetonitrile gives 3-amino-5-methylthio-1,2,4-triazole while reaction of hydrazine with dimethyl N-cyanoimidocarbonate produces 3-amino-5-methoxy-1,2,4-triazole; Journal of Organic Chemistry, 39, 1522 (1974). ##STR22##

Reaction of substituted hydrazines with N-cyanothioimidocarbonates (prepared according to the procedure given in D. M. Wieland, Ph.D. Thesis, 1971, pp. 123-124) yields disubstituted aminotriazoles as shown below. ##STR23##

Many of the aminoheterocyclic intermediates where R is methyl may be prepared by a two-step procedure as described below. ##STR24##

A solution of the amine in concentrated hydrochloric acid is treated with sodium nitrite solution and the chloro compound is isolated in the usual manner by filtration of the acidic solution. A representative procedure is described by Bee and Rose in J. Chem. Soc. C, 2031 (1966), for the case in which Z═CH, and X═Y═OCH₃. Displacement of the chlorine may be accomplished by heating with an excess of methylamine in water to obtain the methylamino heterocycle (IIIg).

Agriculturally suitable salts of compounds of Formula I are also useful herbicides and can be prepared in a number of ways known to the art. For example, metal salts can be made by contacting compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide, carbonate or hydride). Quaternary amine salts can be made by similar techniques.

Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contacting of an aqueous solution of a salt of a compound of Formula I (e.g., alkali metal or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water, e.g., a copper salt, and can be separated by filtration.

Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged. In this method, the cation of the resin is exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble, e.g., a potassium, sodium or calcium salt.

Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like.

The compounds of this invention and their preparation are further illustrated by the following examples wherein temperatures are given in degrees centigrade and parts by weight unless otherwise indicated.

Formulations

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide", 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC publishing Corp., Ridgewood, N.J., as well as Sisely and Wood "Encyclopedia of Surface Active Agents", Chemical publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by sprayiny the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

The ingredients are blended and milled to pass through a 100 mesh screen. This material is then added to a fluid bed granulator, the air flow is adjusted to gently fluidize the material, and a fine spray of water is sprayed onto the fluidized material. The fluidization and spraying are continued until granules of the desired size range are made. The spraying is stopped, but fluidization is continued optionally with heat, until the water content is reduced to the desired level, generally less than 1%. The material is then discharged, screened to the desired size range, generally 14-100 mesh (1410-149 microns), and packaged for use.

Utility

Test results indicate that the compounds of the present invention are active herbicides. They should have utility for broad-spectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Alternatively, many of the subject compounds should be useful for plant growth modification, such as growth retardation.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as selective or general herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.05 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for plant growth modification or for situations where only short-term persistence is required.

The compounds of the invention may be used in combination with any other commercial herbicide examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types. The compounds may also be used in combination with mefluidide.

The herbicidal and plant growth modifying properties of the subject compounds were discovered in the greenhouse. The test procedures and results follow. ##STR39##

TEST A

Seeds of crabgrass (Digitaria sp.), barnyard-grass (Echinochloa crusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia), morningglory (Ipomoea sp.), cocklebur (Xanthium pensvlvanicum), sorghum, corn, soybean, cotton, sugar beet, rice, wheat and purple nutsedge (Cyperus rotundus) tubers were planted in a growth medium and treated pre-emergence with the chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were compared to controls and visually rated for response to treatment. The ratings, summarized in Table A, are based on a numerical scale extending from 0=no injury, to 10=complete kill. The accompanying descripti ve symbols have the following meanings:

C=chlorosis/necrosis;

E=emergence inhibition;

G=growth retardation;

H=formative effect;

X=axillary stimulation; and

U=unusual pigmentation.

Although some of the test compounds show low herbicidal activity at the low rate tested (50 g/ha), they would be expected to show increased herbicidal activity at higher application rates.

One pan was planted with blackgrass (Alopecurus myosuroides) sugar beets, nutsedge (Cyperus rotundus) tubers, crabgrass (Digitaria sanouinalis), sicklepod (Cassia obtusifolia), teaweed (Sida spinosa), jimsonweed (Datura stramonium), velvetleaf (Abutilon theophrasti), and giant foxtail (Setaria faberii). The other pan was planted with wheat, cotton, rice, corn, soybean, wild oats (Avena fatua), cocklebur (Xanthium pensylvanicum), morningglory (Ipomoea hederacea), johnsongrass (Sorghum halepenese) and barnyardgrass (Echinochloa crusgalli). The plants were grown for approximately fourteen days, then sprayed post-emergence with the chemicals dissolved in a non-phytotoxic solvent.

Pre-emergence

Two round pans (25 cm diameter by 12.5 cm deep) were filled with Woodstown sandy loam soil. One pan was planted with blackgrass (Alopecurus myosuroides), sugar beets, nutsedge, crabgrass, sicklepod, teaweed, jimsonweed, velvetleaf, and giant foxtail. The other pan was planted with wheat, cotton, rice, corn, soybean, wild oats, cocklebur, morningglory, johnsongrass and barnyardgrass. The two pans were sprayed pre-emergence with the chemicals dissolved in a non-phytotoxic solvent.

Treated plants and controls were maintained in the greenhouse for 28 days, then all treated plants were compared to controls and visually rated for plant response.

Response ratings are based on a scale of 0 to 10: where 0=no effect, and 10=complete control. The type of response is indicated by letters where G=growth retardation.

Response ratings are contained in Table B.
